Mercon and Mercon V (mix?)
OK... according to information I've gathered from around the web, and from the bottles of ATF I've used (and have had used), Mercon V is now the recommended replacement fluid for my 1996 Ranger Supercab 3.0L 2WD 4r55e (I think) tranny, and Mercon V is in there now (flush and fill, so it IS mixed with Mercon to some small degree).
Mercon was specified in the truck's owners manual, which has warnings against mixing ATF types. Apparently Ford has issued one or more TSB's indicating that Mercon V is good to add or replace that override these warnings for vehicles that came with Mercon.
So... my questions:
1) Is Mercon V good in a trans that originally specified Mercon?
2) Will the current mix of Mercon V with what remained of the Mercon cause (new) problems down the road?
3) Can the trans be topped off with regular Mercon without doing any damage? (I have several quarts of this left).
Thanks in advance!
